Tie a piece of elastic around the sponge and then around your waist and use the sponge as resistance.
2. Rubbish bin
Make sure the bin is clean and empty and do butterfly kick under the water with fins on, holding the bin out in front of you. It will catch all of the water and make it very difficult to go fast.
3. Medicine ball
Do vertical kick with a group of friends and throw the medicine ball to each other. If you’re by yourself, try and keep the medicine ball above the water.
Do butterfly kick on your back with fins on trying to keep the brick above the water. Do you have a big cinder block? Try and run under the water as fast as you can while holding your breath.
6. Inner tyre tube
Cut up the tyre tube into bands and put that around your feet to use when pulling.
7. Tennis balls
Instead of doing fist freestyle, hold tennis balls in your hand and you’ve got a replacement for fist freestyle drill.
